Final answer:
The expression 15.2 × 0.69 simplifies to 10.488. Option (A) is correct.
Step-by-step explanation:
Multiplication is one of the basic mathematical operations. When two or more numbers are multiplied together, the answer obtained is called the product. In the case of the multiplication of two numbers, the first number in which the other is being multiplied is called the multiplicand.
Shift-and-add multiplication is similar to the multiplication performed by pa- per and pencil. This method adds the multiplicand X to itself Y times, where Y de- notes the multiplier.
The multiplication of numbers say, 'a' and 'b', is stated as 'a' multiplied by 'b'. In Maths, the basic explanation of multiplication is adding a number, concerning another number, repeatedly. For example, if we are multiplying 2 by 3, that means 3 is added to itself two times, i.e. 3 + 3 = 6.
To simplify the expression 15.2 × 0.69, you need to multiply the two numbers together.
15.2 × 0.69 = 10.488
Therefore, the answer is A. 10.488.
